本発明は、ケーブルのシース＋ｔｈや各種の成形品等に
用いられるポリクロロプレンゴム組成物に間する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a polychloroprene rubber composition used for cable sheaths and various molded products.
（従来の技術）
ポリクロロプレンゴムは、その優れた難燃性、可撓性、
耐候性、耐オゾン性等の特性からケーブルのシース材料

たもの等がある。(Prior art) Polychloroprene rubber has excellent flame retardancy, flexibility,
Due to its weather resistance and ozone resistance properties, it is used in many applications such as cable sheath materials, backings, and hoses.
There are compositions suitable for cable sheath materials by adding various Bq agents and inorganic fillers to polychloroprene rubber.

いという問題がある。However, polychloroprene rubber has a polymer structure that retains type 2 packing even after vulcanization, so it has the drawback of low heat resistance. It is known that rapeseed oil is suitable as the oil and octamine, Alanox, etc. as the anti-aging agent. However, even if these oils and anti-aging agents are added, they cannot be sufficiently applied to applications such as mobile cables that require both low-temperature properties such as flexibility and mechanical properties at low temperatures and heat resistance. There is a problem.

It was agreed that a good polychloroprene rubber composition would be provided for t1.

In the rubber composition formed by blending 8011 parts by weight and an additive, the polychloroprene rubber is trans-1,4
- A heat-resistant polychloroprene rubber composition characterized by containing 50 to 80 M% of polychloroprene rubber in which polychloroprene is 90% by weight or more.

することでざらに耐熱性を向上させている。Polychloroprene has two structures, trans-type and cis-type, depending on its polymer structure, but in the present invention, heat resistance and heat resistance are achieved by blending trans-1,4-polychloroprene in an appropriate ratio as polychloroprene rubber. It has good low-temperature properties, and the combination of zinc powder and thermal black significantly improves heat resistance.

If the amount of each compounded is less than this, the improvement in heat resistance will be insufficient, and if the amount is more than this, the mechanical properties of the resulting composition will be deteriorated. As thermal black,
FT carbon, MT carbon, etc. can be used alone or in combination.
